2 Claims.

This invention relates to a flywheel rotating tool.

Speaking more specifically the invention pertains to a tool having jawsapplicable to the flywheel of the engine of an automobile which renderthe tool usable to turn said flywheel in the direction and to the extentthat may be necessary to place the movable parts of the engine in theposition desired by the workman.

In diflerent types of cars the flywheel rim varies in breadth from theedge of the ring gear, therefore necessitating the use of an adjustabletool to grip the rims of the various types of flywheels.

Also, in some automobiles flywheels of a ringless type are used. Inorder to adapt the tool for use on that type of flywheels the tool isprovided with a reversible jaw having a projecting part which may beutilized either to grip the interior of the first mentioned type offlywheel, or to engage the clutch cover carried by the last mentionedtype of flywheel.

Among objects of the invention are to provide a flywheel turning toolwhich is of a simpler structure, which can be manufactured at a lowercost, and which is furnished with an improved tool, separately shown,the gripping jaw being adjusted for application to the ring gearcarrying type of flywheels, part of the handle being broken out toshorten the view.

Fig. 2 is a view showing mostly in section, but partly in elevation, thetool as applied to the rim portion of the ring gear carrying type offlywheel. A portion of the flywheel and the tools handle are brokenaway.

Fig. 3 is a sectional view of the structure of Fig. 2, the plane ofsection being indicated by line 3-3 on the latter view.

Fig. 4 is a View of the applicator part of the tool showing thedetachable gripping jaw a justed for use on flywheels of the rimlesstype.

Referring in detail to the drawing, my newly invented tool comprises anon-adjustable, channel shaped strap iron jaw 5 having a body portion 6,a shorter auxiliary flange l at one side of the channel and a longermain flange 8 at the opposite side of the channel. The body portion 6 ofthe jaw 5 is centrally apertured to have tightly fitted into it andwelded one end ,of a tool handle .9 consisting of a rod whereby the toolis opfated, said handle projecting from that side of said jaw which isopposite to said channel and having a milled portion 9a. Said jaw bodyportion 6 lies in a plane which extends at a right angle to said rod.

The main flange 5 of the jaw 5 has a central countersunk aperture tappedinto it to provide for anchoring within it a pin it having an internalhead 15a within the countersink ,andhaving a winged nut I i screwingonto it. Said pin It is utilized to secure an adjustable and reversiblejaw E2 to the aforesaid non-adjustable jaw 5. Said adjustable jaw is anL-shaped piece of strap metal having a shorter basal limb 53 and alonger upstanding (as viewed in Fig. 1) limb it. A. Iongitudinal slot 55extends through said limb if; to receive adjustably the aforesaid pinHi, the winged nut ll being tightened to secure the two jaws in thedesired adjusted relation to each other.

The slotted end portion of the limb It of the adjustable jaw is showntransversely ribbed or serrated at IS on one side or face and at it onits other face and (as best shown in Fig. 2) the limb 8 of thenon-adjustable jaw has a likewise ribbed or serrated outer face it,these roughened surfaces cooperating to aid in securely holding the jawM in its adjusted position whether its basal limb I3 is directedinwardly as in Fig. l in an underlying relation to the channel of jaw orout wardly as in Fig. 4.

In Figs. 2 and 3 the device is shown clamped to the peripheral portionof a conventional engine flywheel 26. Around one of its faces this fly--wheel has near its periphery an annular lateral rib or rise 2! which isrectangular in cross section and is spaced somewhat inwardly from theperiphery of the wheel thus producing an angular peripheral recess 22 toreceive the toothed flywheel ring gear 23 carrying teeth 24. The applieddevice is shown in Figs. 2 and 3 gripping both said ring gear 23 andannular rise 2|, the efficiency thereof being increased by reason of thejaw l and the work to which it is applied being in axial alinement withthe rod 9.

When the rimless type of flywheel is encountered, before the channelshaped jaw 5 of the tool is applied to the rim of the wheel (which inthat case is narrow enough to be spanned by said jaw) the detachable jawi2 is attached to the jaw 5 in the position shown in Fig. 4 so that thebasal limb l3 of said jaw l2 will be adjustable in a take hold of theintervening part of the flywheel in a pipe-wrench fashion.

I claim:

1. A flywheel gripping tool comprising a handle consisting of a rod, achannel shaped strap metal jaw seatable astride the periphery of thering gear of a flywheel permanently attached to one end of said rod,said rod extending from the central portion of that side of said jawwhich is opposite to its channel so that the jaw is in axial alinementwith the rod, said jaw having side flanges which are connected by a bodyportion having in it a central seat for the attached end of the rod,said body portion lying in a plane which extends at a right angle tosaid rod, an L- shaped strap metal jaw having a longer and a shorterlimb, there being a longitudinal slot through said longer limb, ascrewthreaded pin secured to one of said side flanges of said channelshaped jaw, said pin projecting from the outer side of said flange inrelation to the channel to pass slidably through and project beyond theslotted portion of said L-shaped jaw, and a nut 4 applicable to theprojecting portion of said pin to clamp said jaws to each other eitherwith the shorter limb of said L-shaped jaw underlying said channelshaped jaw or extending in the opposite direction.

2. A tool for rotating flywheels comprising a saddle-forming jawconsisting of a channel shaped metal strap having a web portion whichunites flanges of unequal length, a handle-forming rod secured in anendwise manner to the central portion of said web in a right angularlyprojecting relation to that side of the latter which forms the back sideof said channel opening, and an L-shaped jaw consisting of two limbs oneof which is longer than the other, said longer limb being adjustablysecured in an overlapping manner to the longer flange of saidsaddle-shaped jaw, the other limb of said L-shaped jaw forming a jawelement which cooperates with said saddle-shaped jaw to grip the rimportion of the flywheel.
